Name

It is derived from the word infatarat in the first verse. Infitar is
an infinitive which means to burst or split asunder, thereby implying
that it is the Surah in which the splitting asunder of the sky has been
mentioned.

Period of Revelation

This Surah and the Surah At-Takwir closely resemble each other in their
subject matter. This shows that both were sent down in about the same
period.

Theme and Subject Matter

Its theme is the Hereafter. According to a tradition related in Musnad
Ahmad, Tirmidhi, Ibn al-Mundhir, Tabarani, Hakim and Ibn Marduyah, on
the authority of Hadrat Abdullah bin Umar, the Holy Messenger (upon
whom be peace) said: "The one who wants that he should see the
Resurrection Day as one would see it with one's eyes, should read Surah
At-Takwir, Surah Al-Infitar and Surah Al-Inshiqaq".

In this Surah first the Resurrection Day has been described
and it is said that when it occurs, every person will see whatever he
has done in the world. After this, man has been asked to ponder the
question: "O man, what has deluded you into thinking that the God, Who
brought you into being and by Whose favor and bounty you possess the
finest body, limbs and features among all creatures, is only bountiful
and not just? His being bountiful and generous does not mean that you
should become fearless of His justice."Then, man has been warned, so
as to say: "Do not remain involved in any misunderstanding. Your
complete record is being prepared. There are trustworthy writers who
are writing down whatever you do." In conclusion, it has been
forcefully stated that the Day of Resurrection will surely take place
when the righteous shall enjoy every kind of bliss in Paradise and the
wicked shall be punished in Hell. On that day no one shall avail
anyone anything. All powers of judgment shall be with Allah.
